TouZZ whom it may concern.-

' speed with the ordinary constructionof carbureter an insufficient. quantity of air is admitted into the mixing-chamber, resulting in great waste of fuel and energy. j

The object of my invention is to provide a simple and eflicient device for overcoming this difliculty. I

Other objects of, theinvention will appear from-the description following hereinafter, and the features of novelty will be pointed out in the appended claims. The drawing represents a diagrammatic view of a carbureter and governor of an automobile'with my invention attached thereto.

A is the power-shaft, connected with the engine in any suitable manner, on which is mounted the fly-wheel B. I

O is a centrifugal governor controlling the speed of the engine, and consists of two bellcranks D, pivoted at D to supports forming part of or secured to the web of the fly-wheel B. To the one end of each of said bell-cranks C are attached the governor-weights E, connected by a spring F. The other end of each of said bell-cranksengages a sliding sleeve or collar G on the shaft A.

H is a lever suitably pivoted at H to a stationary support, (not shown,) its one endengaging the sleeve G, as at H The said lever H is connected at H with a sleeve or colsliding type and is interposed between the mixing-chamber of thecarbureter and the inlet N.

O is a lever suitably pivoted to a stationary Support at O and pivotally connected at O Specifidation of Letters Patent. Application filed April 1,1904. SerialNo. 201,088.

, with a rod P, leading to th'efront of the vehicle in such a position as to be easily accessible to the operator. The end 0 of said lever 0 is arranged under certain. conditions to engage the collar L. v p

R is a valve in the inlet-pipe N, secured to a stem S, suitably supportedin abearing S, said valve B being normally closed tothe atmosphere by' a coil spring T.

'R is an air inlet communicating with the atmosphere and also having connection with the pipe N. The free end of thevalve-stem S is connected to'an extension of the lever H by a pin-and-slot connection S It will be understood that all the parts described are suitably supported upon stationary parts 'of the machine, which I have not deemed necessary to illustrate.-

The operation of the mechanism described is as follows: As the speed of the engine increases the governorweights E are forced outward from the shaftA by centrifugal force,

and this motion is transmitted to the bellcranks D and through the said bellcranks to the s liding sleeve orcollar G. The motion transmitted to the said'sleeve G will swing the lever H on its pivot H and through its con-- be desired to continue to run the engine at a high speed, or, in other words, to overcome the action of the governor and its connected parts just described, the operator moves the rod P to the left, swinging the lever O on its fulcrum'O and bringingthe end 0 into engagement with the collar L, and thus preventing the compressing of the spring K from closing the throttle-valve. As the governorweights are now 'moved away from the shaft A by centrifugal force, (the engine continuing to run at a high speed,) the lever H will be swung on its pivot, as before described, and motion to the left will be transmitted to the stem S, thus opening the air-inlet valve R, admitting an extra quantity of air to the .engine, and thus insuring a mixing of the air and fuel in correct proportion to obtain the best results while running at a high speed. It will be understood that as long as the operator continues to hold the projection 0 against the collar L the action of the governor will have no effect on the throttle-valve, but will hold the valve R open.

Various modifications may be made without departing from the nature of my invention.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a carbureter, a connection for conducting the explosive mixture, including air, from such carbureter to the engine, a throttle-valve in said connection, and a separate valved inlet for the admission of air only in said connection, between said throttle-valve and the engine and means for automatically moving said air-inlet valve as described.

2. The combination of a carbureter, a connection for conducting the explosive mixture from said carbureter to the engine, athrottlevalve in said connection. a separate air-inlet valve located in said connection between the throttle-valve and the engine, a governor oper'ated by the engine and an operative connection from said governor to the separate inlet-valve, to allow air to join the explosive mixture after it has passed the throttle-valve in case of higher speed.

3. The combination of a carbureter, a connection for conducting the explosive mixture from said carbureter to the engine, a throttlevalve, a governor for closing said valve as the speed increases, means under the control-of the operator for holding the throttle-valve open notwithstanding the action of the governor, an air-inlet valve in said connection, and means operated by the governor for opening said air-inlet valve when the speed increases and the throttle-valve is held open.

4:. The combination of a carbureter, a connection for conducting the explosive mixture from said carbureter to the engine, an air-inlet in said connection, a valve controlling said inlet, a throttle-valve, a governor controlled by the engine and operative connections from the governor to the throttle-valve and to said air-inlet valve to cause the throttle-valve to close and the said air-inlet to open when the speed of the engine increases.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
